Tips for Buying a Flatbed Truck Under $45K
Before you commit to buying a used or upfitted flatbed truck, here are a few expert tips to ensure you get the most value for your budget:
1. Know Your Payload Needs
Determine how much weight you’ll be carrying daily. Trucks like the Ram 5500 or Ford F-450 are better for extremely heavy loads (5,000+ lbs), while an F-350 may suit lighter jobs.
2. Consider Chassis Cab vs. Factory Flatbed
Some models come with pre-installed flatbeds, while others are chassis cab trucks that have been upfitted. Upfitted models can offer better customization but vary in build quality depending on who did the work.
3. Inspect the Flatbed Itself
Check the condition of the flatbed frame. Look for:
- Rust or corrosion on steel frames
- Cracks, dents, or loose welds
- Proper function of stake pockets, tie-downs, and toolboxes
4. Engine Type: Diesel vs. Gas
Diesel engines (like the 6.7L Power Stroke or Cummins) are better for heavy hauling, offer higher torque, and longer durability—but may cost more to maintain.
Gas engines offer lower upfront costs and simpler maintenance.
5. Check Local DOT Compliance
Make sure the truck meets Department of Transportation (DOT) requirements in your state—especially if you’ll be using it for commercial purposes.
